A buddy of mine has a Camaro with the LS1 engine. He put a flowmaster muffler in place of the stock muffler and now it throws o2 sensor codes. Anyone else have this problem?

Never heard of that..
Me neither. I would think its more of a coincedence (sp). Its probably the 02's or the cats. A auto shop should be able to tell you.
They arent related. What codes is he throwing? Why did he go with a slowmaster? :nana:

Catback or just muffler. Just muffler nah. If catback maybe lose connection on O2 or overheated the pipe while welding closeby. Only thing I can think of. I say just that the O2 is going bad. Did you install headers with that system? Y-pipe? Exhaust leak up front somewhere or damage from lift etc.... ???? Those are just some things I'd check.... But, most like just a bad O2.
What are the codes (front or rear o2)? There is most likely either a leak, damage to the cat, or a bad sensor.
